Advice for my job

So I got a job offer from a small construction company after months of applying to multiple jobs. After taking some time to consider I let the employer know that I would take the job. I gave my employer a call today to ask questions about my first day of work. He ended up yelling at me 2 mins into the call and saying he is uncomfortable with me for asking too many questions and hung up on me. At this point I don't know what to do. I would prefer to keep the job but I don't know if I still have the job and I don't want to call back asking either.

What do you guys suggest I do?
